Abstract

Apparatus, for transmitting measurements made at the well bottom during drilling, as pressure pulses applied to the drilling mud and picked up at the surface fitting onto the lower part of the drilling string and provided with at least one depth measuring instrument, transforming the measurements into electrical measuring signals, corresponding to a source of electrical current to which the transformer means are connected, and a valve incorporated in the drilling mud flow line, produces pressure pulses by sudden pressure decreases.
